## Overview

This is a fishing and cottage booking application: Angular client workflows serve guests, customers, and boat/cottage owners, while a Spring Boot API models listings, appointments, reservations, reviews, and user accounts over a PostgreSQL-backed persistence layer. The principal flow is discovery and availability search, reservation creation, then customer and owner follow-up; separate branches support listing management, special offers, reports, and account administration. The tree and README establish product scope, but most controllers and service implementations were not sampled, so those links are shown as unverified rather than asserted calls.
